IN CAN DESGEN T GAS-LIGH'IIN Patented Aug. 5, 1919.

Application filed January 18, 1919. Serial No. 271,799.

To all whom it may concern:

Be it known that I, FRANK PERRY, residing at 68 Dudley road, Tipton, inthe county of Stafford, England, a subject of the King of Great Britainand Ireland, have invented certain new and useful Improvements Relatingto Incandescent Gas-Lighting, of which the following is a specification.

This invention relates to incandescent gas lighting, and has for itsobject to construct improved inexpensive means whereby a small light canbe obtained.

In the accompanying sheet of explanatory drawings:

Figure 1 is a perspective View showing the front and Fig. 2 a like viewshowing the rear of an illuminating device constructed in accordancewith this invention.

In carrying the invention into eflect as shown a burner a fitted with asteatite tip and having a small orifice is used, the burner deliveringonly a small quantity of gas at full pressure. The burner is one of verysmall size giving a bats-wing, rat-tail or other like flame. For examplea burner consuming one-third to one-half a cubic foot of coal gas perhour is sufficient. When supplied with gas at full ordinary townpressure such a burner gives a non-luminous flame without previousadmixture with air. At a convenient distance in front of the burner,which is preferably arranged horizontally, is secured a flat or otherpiece of refractory mesh b of similar material to that used in the usualcylindrical mantles, the plane of the refractory mesh being preferablyat right angles to the axis of the topics of this patent may be obtainedfor five cents each, by addressing the burner. This refractory materialmay be rectangular or circular in shape and is preferably flat or nearlyflat. The refractory material is carried on a metal frame 0 constructedfrom thin sheet or strip and having its edges turned over to grip theedges of the refractory material. Integrally with the frame is aconnecting stem 0? having one end shaped to form a slotted cylindricalgripping piece 6 which can fit over and grip the cylindrical body of theburner. The burner flame impinges on the back of the refractory materialand raises the same to incandescence.

An illuminating device as above described is capable of givingsufficient light for many domestic and other purposes. Also it canreadily be fitted to any standard gas fitting which will take anordinary bats-wing or like burner.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent is An illuminating device comprising incombination a small gas burner from which the gas issues withoutprevious admixture of air, a flat piece of refractory mesh, a lightsheet metal frame having its edges bent over to grip the mesh, a stemformed integral with the frame, and a slotted cylindrical gripping pieceformed with the stem and adapted to grip the body of the burner,substantially as described.

In testimony whereof I have signed my name to this specification.
